The Osprey Women's Ariel 55 Pack is a go-anywhere backpacking pack for 2-5 day trips. The Ariel series is a solid arsenal for summits, nearby woods, and unexplored backcountry. The 55 is the smallest of the group, but capable of carrying loads between 40 and 55 pounds due to the IsoForm4 harness and IsoForm4CM™ hipbelt, where custom moldable is key. Jam your sleeping bag into the bottom zippered section and the divider will keep it separate and allow quick access, while your sleeping pad can be slung to the outside with those useful straps. The top pocket will not only secure your map, compass, knife, and all the other little things, but when you make it to camp, completely remove it and use it as a lumbar pack when you head off for a side-hike. Zippered pockets to ice axe loops, the Ariel is locked and loaded with all the features you'll ever need.

Osprey Airscape
Osprey's AirScape™ mesh covered ridge foam backpanels set a new standard in the industry. With its ability to keep the weight close, provide cushion, allow ventilation and add load carry is quite a list of needs from this unassuming backpanel. It successfully accomplished all of that in a way that allows it to be used in the large gear hauling packs and lightweight day hiking packs.

Osprey Custom Molding
When the loads get heavy, a supportive and effective hipbelt can support that weight. Osprey custom heat molds their hipbelt to you, eliminating hotspots, chaffing and bruising. This combines the best of a stiff, load bearing hipbelt with the cushioned comfort you need most when trekking with all your gear.

Osprey Peripheral Frame
Peripheral frame was a departure from the norm many years ago and it’s still the foundation of our gear hauling packs. A wire frame runs along the outside of the backpanel directly connecting the upper load lifters and the central core of the pack to the hipbelt to transition and spread the load. Allowing natural torsional movement, effective adjustable torsos, and different load range and backpanel builds makes this suspension design truly innovative.

Please note that the info provided above refers to the torso size each pack will fit, and NOT any dimensions of the pack. Below are some steps for how to get your torso length. You should probably have someone help take this measurement for you so it is accurate. And they might accidentally touch your butt.

HOW TO MEASURE TORSO LENGTH:
• Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt.
• From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down.
• Make sure you keep your back as straight as possible while measuring.
• This torso measurement determines what size Osprey pack you should carry. Refer to the size charts above to find your ideal size.
• If you are in between sizes, it is ideal to try them both on before ordering.

HOW TO MEASURE HIPBELT SIZE:
• Measure around your hips at your iliac crest, NOT your waist.
• A properly fitted hipbelt rides centered over the hipbones and needs to be very snug.
• The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the both hip pads when securely tightened.
• Refer to the Hipbelts size chart above to help determine your ideal Osprey pack size, but again, your torso length is what should determine your pack size, NOT the hipbelt.

Purchased for the GF... and she loves it!I personally wear an Aether 70, and picked this up for my girlfriend to use on our trips together. She loves it, some amazing female specific tune ups on this pack when compared to the Aether. She feels similarly to how I feel about my Aether, sure the pack weighs a bit more, but it carries loads like a dream. Worth every penny!

Happy happy happyI'm a first timer as far as hiking packs but this one is proving to be as good as everyone says. My first trip with it was a 3 mile up hill hike in Big Sur (not a huge hike but it gave me a good picture). The thing fit like it'd been broken in and was super supportive. I originally bought the 65 and returned it because I was worried it was too bulky. I'm happy with the 55L. This pack fit everything I needed for a 2 week road trip and I'm not that minimalist when it comes to packing. The pockets on the waist strap are golden. Another awesome feature is the bottom entry zipper. That was one of my main stipulations when looking for a pack and it really does make all the difference. The water bladder capability is nice, too. I'll check back in after I conquer bigger terrain!

AWESOME pack!!!My wife needed a new multi-day pack she is tall and thin most packs just look and feel ridiculous on her. Well, after some research we found a new "GO TO" the Areil 55 Osprey pack for women is perfect. It really fits her well and she loves the look, not really important but it's true. This pack has only seen some lite hiking so far as we are preparing for a huge trip. Hopefully this helps thanks for reading.

Osprey knows what's up for women.I spent months researching packs before I finally settled on this one. I chose it for comfortable fit and size. I lived out of it for five months while backpacking through southwest China. It saw everything a pack could see, and came out on top. For a smaller person (I'm 5'4 and 110 pounds) this pack is PERFECT. The weight balances well, and I never felt like I would topple over. The extra compression strap is great when the pack isn't super full, and the detachable brain came in handy when I didn't want to use my daypack. My only wish is that this pack had a few more pockets like Gregory does, but I ended up being fine without them (less opportunity to lose things). Instead, I used soft cloth bags to organize tiny things. All in all, I'm very excited to use it for future adventures. If you like packing lots of things, and can handle the weight, definitely bump up to a 65L model.

Great backpack.This backpack is awesome. I upgraded from a day pack, and this holds tons of stuff, but can compress down when less full, so it doesn't look enormous. The straps at the base were great for hauling the tent. The side pockets each held a 1 liter Camelbak waterbottle without any problem, and are easily accessible when wearing the pack. The pockets on the waist strap are super convenient for a small camera, chapstick, hand sanitizer, etc. The waist strap did leave some sore, rub spots on my hips after 10 hours of hiking, but I think it had more to do with me not being used to carrying a heavy pack, and the pants I was wearing did have any stretch in the waist. I almost got to test the whistle on a black bear, but my pack was outside the tent, and I was inside. I'll remove the whistle and keep it on me next time. Overall, great looking pack that works really well, and it was a total bargain on moosejaw.

Love!I had been dreaming of this pack for a while and got an awesome deal at Moosejaw. This pack fits well and is so comfy. 3 ways to get to your stuff from top, middle and bottom of the pack. Loops and pockets and so practical. At almost 5'4" I got the small one (had tried it on and been measured before) and I could not be happier.

Comfortable and roomy, rugged where it needs to be, just light enoughgreat pack for longer solo trips in the back country. very comfortable mold-able hipbelt. I carried about 80 Lbs in it on my last day this season without failure. As all osprey packs it has taken its beating and never failed to perform perfectly.
